SNMP::Info::Layer2::HP - SNMP Interface to HP Procurve Switches
=head1 AUTHOR
Max Baker
=head1 SYNOPSIS
# Let SNMP::Info determine the correct subclass for you.
my $hp = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.\n";
my $class = $hp->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";
=head1 DESCRIPTION
Provides abstraction to the configuration information obtainable from a
HP ProCurve Switch via SNMP.
Note: Some HP Switches will connect via SNMP version 1, but a lot of config
data will not be available. Make sure you try and connect with Version 2
first, and then fail back to version 1.
For speed or debugging purposes you can call the subclass directly, but not
after determining a more specific class using the method above.
my $hp = new SNMP::Info::Layer2::HP(...);

Version 0.4 - Removed F<ENTITY-MIB> e_*() methods to separate sub-class -
SNMP::Info::Entity
=head1 GLOBALS
These are methods that return scalar value from SNMP

=item $hp->cpu()
Returns CPU Utilization in percentage.
=item $hp->log()
Returns all the log entries from the switch's log that are not Link up or
down messages.
=item $hp->mem_free()
Returns bytes of free memory
=item $hp->mem_total()
Return bytes of total memory
=item $hp->mem_used()
Returns bytes of used memory
=item $hp->model()
Returns the model number of the HP Switch. Will translate between the HP Part
number and the common model number with this map :

=item $hp->os()
Returns hp
=item $hp->os_bin()
C<hpSwitchRomVersion.0>
=item $hp->os_ver()
Tries to use os_version() and if that fails will try and cull the version from
the description field.
=item $hp->os_version()
C<hpSwitchOsVersion.0>
=item $hp->serial()
Returns serial number if available through SNMP
=item $hp->slots()
Returns number of entries in $hp->e_name that have 'slot' in them.
=item $hp->vendor()
hp
=item $hp->fan()
Returns fan status
=item $hp->ps1_status()
Power supply 1 status
=item $hp->ps2_status()
Power supply 2 status
=item $hp->peth_port_power()
Power supplied by PoE ports, in milliwatts
("hpicfPoePethPsePortPower")

=head1 TABLE METHODS
These are methods that return tables of information in the form of a reference
to a hash.
=head2 Overrides
=over
=item $hp->interfaces()
Uses $hp->i_description()
=item $hp->i_duplex()
Returns reference to map of IIDs to current link duplex.
=item $hp->i_duplex_admin()
Returns reference to hash of IIDs to admin duplex setting.
=item $hp->vendor_i_type()
Returns reference to hash of IIDs to HP specific port type (hpSwitchPortType).
=item $hp->i_name()
Crosses i_name() with $hp->e_name() using $hp->e_port() and i_alias()
=item $hp->peth_port_ifindex()
Returns reference to hash of power Ethernet port table entries map back to
interface index (c<ifIndex>)
=back
=head2 Topology information
Based upon the firmware version HP devices may support Cisco Discovery
Protocol (CDP), Link Layer Discovery Protocol (LLDP), or both. These methods
will query both and return the combination of all information. As a result,
there may be identical topology information returned from the two protocols
causing duplicate entries. It is the calling program's responsibility to
identify any duplicate entries and remove duplicates if necessary.
=over
=item $hp->hasCDP()
Returns true if the device is running either CDP or LLDP.
=item $hp->c_if()
Returns reference to hash. Key: iid Value: local device port (interfaces)
=item $hp->c_ip()
Returns reference to hash. Key: iid Value: remote IPv4 address
If multiple entries exist with the same local port, c_if(), with the same IPv4
address, c_ip(), it may be a duplicate entry.
If multiple entries exist with the same local port, c_if(), with different
IPv4 addresses, c_ip(), there is either a non-CDP/LLDP device in between two
or more devices or multiple devices which are not directly connected.
Use the data from the Layer2 Topology Table below to dig deeper.
=item $hp->c_port()
Returns reference to hash. Key: iid Value: remote port (interfaces)
=item $hp->c_id()
Returns reference to hash. Key: iid Value: string value used to identify the
chassis component associated with the remote system.
=item $hp->c_platform()
Returns reference to hash. Key: iid Value: Remote Device Type
